ABRADlNG-COVERING FOR BUFFERS.

SPECIFICATION forming part of Letters Patent No. 407,247, dated July 16,1889.

Application filed December 7, 1888. Serial No. 292,925. (No model.)

To aZZ whom it may concern.-

Be it known that I, ANDREW IV. ROGERS, of Beverly, in the county ofEssex and State of Massachusetts, have invented a new and usefulImprovement in Abrading-Coverings for Buffers; and I do hereby declarethat the following is a full, clear, and exact description of the same.

My invention, hereinafter explained, re-

lates to the a-brading-coverings for buffers, such as are used to finishthe soles of boots or shoes.

The invention consists of a double-faced reversible cover, which isprovided with reversible attaching devices adapted to connect it to thefoot, and adapted,when one face is worn, to be turned to bring the otherinto use.

It is illustrated in the accompanying drawings, in which- Figure 1 showsin perspective the double cover with its attaching devices inserted inslits in either face. Fig. 2 is a section thereof on line 1 1 of Fig. 1.Fig. 3 shows in perspec- 2 5 tive a modification in which theattachments are formed by tongues cut out of the material of thecovering. Fig. 4c shows another modification in section, in which thetongues are inserted between the two thicknesses of c the sand-paper andproject outward.

In the drawings, the abrading-covering A is formed of two thicknesses aa of sand-paper, this material representing here any of the variousforms of its class. These are united, preferably, by glue, and aremolded,

preferably, in concavo-convex form, and, being of stiff material, whenfinished may be sprung into reverse positions to bring one or the otherof the faces into convex working form, as the case may require.

In the form first shown, the attachments or projections by means ofwhich the covering is adapted to be connected to the ordinary foot of abuffer consists of two or more (preferably three or four) strips B, ofstiff sheet metal, the lower ends of which are bent at right angles toform feet I), which are illserted into slits c in the faces of thecovering and between the two parts thereof. \V hen so inserted thecovering may be attached to the foot D, as described in an applicationfiled by me in the United States Patent Office, of even date herewithand having Serial No. 292,921, or in any other convenient or wellknownway.

The second form of connecting projections or attachments adapted to beused with my invention is shown in Fig. 3, in which the strips 6 are cutout and formed of the material of the double covering, being integral 6otherewith on one end. They are reversible also, and may be turned eitherway, according to the face used of the covering, and are the same turnedin either direction. The other form of connecting projections consistsof straps f, the ends of which are inserted between the two parts (0 a,on the edges and project outward, being held by the glue or in anyconvenient way. They may be turned up over the edge of the foot and beconnected 7o therewith in any suitable way. These two last-mentionedforms of connecting projections for the covering are not herein broadlyclaimed, being shown and claimed in applications filed by me in theUnited States Fat cut Office, of even date herewith and seriallynumbered 292,926 and 292,927.

It will be plain that the double reversible covering has the advantageof economy, as one thickness of the sand-paper re-enforces the other togive it the required stiffness ordinarily imparted by a re -enforcementof stilf paper. There are also other advantages in respect to bulk andconvenience in use.

The general form of the covering and its attachments is a highlyadvantageous one, and is shown and claimed in another application filedby me in the United States Patent Office, of even date herewith andserially numbcred 292,924. (Referred to above.)

One special advantage of the first two forms of connecting projectionsis that they are adapted to a reversible covering, and in eitherposition it has its projection between the margin and center.

I do not herein claim an abrading-covering for the foot of a bufferhaving connections to hold it to the foot, attached to the cover between the center and the margin, as that is not my invention broadly, asI am aware that 100 the broad invention is that ofFreeman H. Winslow andthe subject of a pending application, Serial No. 292,932, of December7,1888.

I claim as my invention-- 1. A reversible abrading-covering for butfers,consisting of a flexible disk of concaveconvex form and abradingmaterial on both sides of said disk, combined with reversibleconnections attached to said coverfor holding it to the foot of thebuffer, substantially as described.

2. A reversible abrading-covering for buffers, composed of two disks ofabrading material placed back to back, and having slits in each disk, incombination with fastening devices adapted to the slits in the disk,substantially as described.

3. A reversible abrading-covering for buffers, composed of two disks ofabrading-covering placed back to back and having slits in each disk,combined with the stiff strips B,

having'bentlower ends adapted to the slits in the disk, substantially asdescribed.

4. The combination .of a buffer-foot, a
